Create a secure Linux- based wireless access point. Wi- Fi Protected Access version 2 (WPA2) is becoming the de facto standard for securing wireless networks, and a mandatory feature for all new Wi- Fi products certified by the Wi- Fi Alliance. We all know the security weaknesses of its predecessor, WEP; this time they got it right. Here's how to implement the WPA2 protocol on a Linux host and create a secure wireless access point (WAP) for your network.
Most consumer- grade commercial WAPs operate in the same simple manner: they create a bridge between a wired (Ethernet) network interface and a wireless one. That's exactly what we'll do too. The WAP part will be handled by the hostapd daemon, so you must pick a wireless interface it supports. Among the supported NICs are those with Prism 2/2. Atheros ar. 52. 1x, and Prism GT/Duette/Indigo chipsets; a list is available on the hostapd homepage, along with links for Linux drivers for each chipset. I have an Atheros AR5. PCI card installed on my WAP, which works great with the latest stable version of MADWifi drivers and is supported by hostapd.

Create a secure Linux-based wireless access point. Check out my previous article on how to create such a setup with OpenBSD.
Although any Pentium (or newer) system will work, some PCI wireless cards require PCI 2. You will also need an Ethernet interface that's supported by Linux for connecting your WAP to the LAN; most on- board interfaces will work just fine. My setup is based on Debian Testing (Etch), but any GNU/Linux distribution with a recent 2. The kernel must support 8. Ethernet Bridging (CONFIG_BRIDGE) and Wireless LAN (CONFIG_NET_RADIO). Most default stock kernels have these features enabled, but if you prefer to build your own kernel, make sure to include these options. The only other packages you need to install, besides hostapd, are bridge- utils and wireless- tools.

Major GNU/Linux distributions offer binary packages for all these programs, but if you prefer to build them from source, you can find more information on their homepages. Before bridging together the two interfaces we must put the wireless interface (in my case ath. Master mode. Usually this is as simple as running iwconfig ath. Master, but since wlan support in Linux is not yet standardized, some drivers may need additional configuration.
If you have an Atheros- based interface you also need to run the following: wlanconfig ath. After that, running iwconfig ath. Master, among others. Now let's create the bridge. We'll assume that the Ethernet interface is eth. And for stopping the bridge, you should run. You can optionally give an IP address to the br.
WAP host from the network, using for instance SSH. Each distribution offers its own way to configure the network; if you use Debian (or any Debian- based distribution, such as Ubuntu) you can wrap up all the previous commands by simply adding the following to your /etc/network/interfaces file. Note that ifupdown handles eth. To verify that the bridge is configured correctly, run brctl show. You should get something like this in return.
STP enabled interfaces. Before starting to mess with hostapd we need a pass phrase for WPA2. As with all passwords, it should be random and thus hard to guess. A nice way to get a random pass phrase is to visit Gibson Research Corp.'s Ultra High Security Password Generator and use the third password it creates - - the one titled 6. A- Z, 0- 9). Having a passphrase that includes non- alpha- numeric ASCII characters (e.
Windows XP - - don't seem to like them. Now create a new text file named /etc/hostapd/wpa_psk and paste your pass phrase as.
PASSPHRASE. The first part with the zeros means 'match all MAC addresses,' and does exactly that. You can also use different passphrases for each client by appending a new line to the file with each client's MAC address and its passphrase.
Make sure that only root has access to that file by running chmod 6. Now create a backup of hostapd's main configuration file, /etc/hostapd/hostapd. Create a new hostapd.
My_Secure_WLAN. #accept_mac_file=/etc/hostapd/accept. WPA- PSK. wpa_pairwise=CCMP. Replace the parts in italics with information that matches your setup. If you want to allow only specific clients to connect, remove the # character from the two lines above and copy the MAC addresses of those clients to /etc/hostapd/accept, and make this file accessible only by root (chmod 6. For more information about the options used, read the comments in the backup file you created previously (hostapd.
Start the hostapd daemon (/etc/init. If the daemon does not come up, increase the debug level (option debug= in hostapd.
Now if you scan for available wireless networks from a client, you should see your ESSID. To connect to the WAP from a Windows XP SP2 client, you need to install Microsoft's KB8. WPA2 support. On a Linux client, install wpa_supplicant and create a configuration file, wpa_supplicant. Debian, installed in /etc/wpa_supplicant/) like the following: update_config=1. My_Secure_WLAN". proto=RSN. WPA- PSK. pairwise=CCMP. CCMP. psk="PASSPHRASE".
Again replace the parts in italics to match your setup and run wpa_supplicant - i eth. D wext - c /etc/wpa_supplicant/wpa_supplicant. This command starts wpa_supplicant in the foreground and tries to connect to the WAP. If the output looks like the following, you're all set. Trying to associate with 0. SSID='My_Secure_WLAN' freq=0 MHz).
Associated with 0. WPA: Key negotiation completed with 0. PTK=CCMP GTK=CCMP]. CTRL- EVENT- CONNECTED - Connection to 0. Give a static IP address to your wireless interface (or run a DHCP client) and try to ping a host inside your LAN to verify that the connection works. Congratulations, you've just built yourself a highly customizable wireless access point. Although this setup is ideal for home or small office usage, you need something more robust in the enterprise, with authentication with a RADIUS server, or even better, a VPN.
